Title: Acoustic reproducer
Inventor: KINOSHITA MASAO
IPC: H04S7/00
Filed: 1978-10-17
Abstract: PURPOSE:To increase the sound field at a narrow place by applying the stereo signal of one side to that of the other side in the opposite phase to each other and setting the hearing state for both the right and left speakers to the state under which the speaker is installed outside. CONSTITUTION:The right and left stereo signals applied to input terminals 10 and 11 are applied to adders 12 and 13, and the signals sent from terminal 11 are given  the opposite phase via phase shifter 14 to be applied to adder 12. Furthermore,  the right and left stereo signals are added together at adder 20, and indirect tone  signal delayed at delay circuit 21 is applied to adder 12. And the indirect tone signal which is phase-reversed via phase shifter 22 is applied to adder 13. The output  of adder 12 is applied to speaker 18 via amplifier 15, and the output of adder 13  is applied to speaker 19 via delay circuit 17 and amplifier 16. And the sound sent  from speakers 18 and 19 is taken outside the place where speakers 18 and 19 are  located. As a result, the sound field can be increased even at a narrow place.

Abstract: PURPOSE:To detect a faulty location quickly without less trouble by providing an oscillator having a different frequency at every intermediate relay device to each intermediate relay device on a transmission line and oscillating oscillators this side from the faulty location only when the transmission line is faulty so as to send an oscillation signal from a supervisory line. CONSTITUTION:Oscillators 14-16 are connected as shown in figure between the cathode of constant voltage diodes 7-9 of the supplying loop of an intermediate relay device in the incoming direction and the supplying loop of an intermediate relay device in the outgoing direction, they are not oscillated normally by rectifier diodes D1-D3, the outputs of the oscillators are connected to the supervisory line 12 and a selection level meter 13 in a terminal station repeater 1-1 is connected to the supervisory line 12. If a fault takes place at a point A in figure and supplying is interrupted, a constant voltage higher than the output voltage of a constant current supply section 11 in reverse direction is applied. Thus, the oscillators 14, 15 are oscillated and signals in frequencies f1, f2 reach the said selection level meter 13 and the signals in the frequencies f1, f2 are detected. Since the signal from the oscillator 16 is not deteced, the said faulty location is discriminated.

IPC: F01L3/24
Filed: 1995-05-01
Abstract: PURPOSE: To reproduce the same state as that obtained when a vehicle is run for a long time by applying a stress to the lip section of a valve stem seal so as to accelerate the wear and settling phenomenon of the lip section in a short time by maintaining a cam shaft chamber in a pressurized state and applying a desired pressure to the lip section. CONSTITUTION: A cylinder head 3 is fixed on a head base 2 and the performance of a valve stem seal 9 is evaluated by driving a cam shaft 14 incorporated in a head cover 30 airtightly fixed to the head 3 by means of a motor. In a chamber 36, an oil pump for circulating oil and oil tank 27 are provided. Since the tank 27 is sealed and the inside of the chamber 36 is maintained in a pressurized state with an air pressure, the lip section 12 of the seal 9 is also maintained in a pressurized state. Because of the pressurization, a stress is applied to the lip section 12 and the setting phenomenon and wear of the section 12 are accelerated. Therefore, the same state as that obtained when a vehicle is run for a long time can be reproduced in a short time and the testing time of the valve stem seal can be shortened.

Title: Thin film transistor and its manufacture
Inventor: NAKAJIMA SETSUO
IPC: H01L29/786
Filed: 1998-04-23
Abstract: PROBLEM TO BE SOLVED: To make efficient sub-threshold characteristic and operate at a high speed and a low power consumption by a method wherein, in steps subsequent to a step of forming an insulation film for use in a gate insulation film, a temperature of the insulation film is lowered more than a film forming temperature thereof. SOLUTION: An aluminum film is formed on an insulation film 301 and anode-oxidated to form an anode oxidation film. An anode oxidation step is carried out and an anode oxidation film 304 is formed on a pattern 303. After a photoresist mask 303 is removed, an anode oxidation step is carried out to form a barrier type anode oxidation film 111. A gate electrode 110 is structured by the pattern 303 which was not anode-oxidated. By using the anode oxidation films 304, 111 and the gate electrode 110 as a mask, the insulation film 301 composed of a silicon nitride and oxide film is patterned and functions as a gate insulation film. After the gate insulation film is formed, the insulation film is avoided being heated at a higher temperature than a temperature for forming the film. Thus, it is possible to manufacture thin film transistors excellent in sub-threshold characteristic.

Title: Discharging device for image recording device
Inventor: FUJII HARUO
IPC: G03G15/02
Filed: 1986-06-04
Abstract: PURPOSE:To obtain electrostatic charging performance stabilized over a long period by detecting the degree of dirt on a corona discharge wire as impedance change and controlling the current and voltage of a high voltage power supply and a bias power supply at their optimum levels in accordance with the detected result. CONSTITUTION:Since the action of a grid wire 16 is not required so much when the corona discharge wire 15 is not dirtied, an impedance detector 19 controls the high voltage power supply 20 so as to reduce corona discharge current on the basis of the change of impedance. On the other hand, the bias power supply 21 is controlled so that the voltage to be supplied to the grid wire 16 is approached to the potential impressed to the wire 15 from the potential required from a photosensitive drum 10. Thereby, even if the voltage to be supplied to the wire 15 is dropped and the corona discharge current is reduced, ions radiated from the wire 15 are uniformed. Consequently, the surface potential of the drum 10 can be uniformly charged.
